Site description El IBA incluye un total de 37,400 ha, de las cuales 11,200 ha de humedales fueron formados por una represa artificial (Embalse Cerrón Grande) construida sobre el río Lempa en 1976. El embalse ahora es un sitio Ramsar y el humedal con mayor concentraciones de patos (Anatidae) en todo Centroamérica (hasta 100,000 contado en un día). Aproximadamente 4,200 ha del área contiene bosque seco.

Key Biodiversity Aparte de concentraciones de decenas de miles de patos (Anatidae) migratorios y residentes, el humedal contiene siete sitios de anidación de al menos siete especies de aves acuáticas, sobresaliendo la única colonia en El Salvador de "Wood Stork" (Mycteria americana). Durante épocas de migración, el humedal atrae grandes bandadas de aves playeras (como "Pectoral Sandpiper" (Calidris melanotos) y "Stilt Sandpiper" (Calidris himantopus). Se han visto concentraciones de más de mil "American White Pelican" (Pelecanus erythrorhynchus).
